EVERETT B. CUSHMAN, OF LINCOLN. NEBRASKA, ASSIGNOB. TO CUSHMAN MOTOR WORKS, OF LINCOLN, NEBRASKA= SPLASH LUBRIC'ATING SYSTEM.

Specification of Letters Patent.

Patented June in. 1on4.

Application filed. September 5, 1912. Serial No. 718,697.

Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful Splash Lubricating System, of which thefollowing is a-specihcation.

This invention relates to improvements in splash lubricating systems especially designed for gasolene motors.

One object of the invention is to provide motors with an oiling device operated by the movement of the crank of the engine.

A further object of the invention is to provide an oiling device which is simple and efi'ective and which is adapted to motors of any ordinary type.

In the accompanying drawin s, illustrat' ing the preferable embodiment of myinvention, wherein it will be understood that various changes and modifications may be .made relating to the detailed construction and arrangement of the parts without departing "from the spirit thereof: Figure 1 is an elevational view of the entire motor, with part of the lower plate removed to expose the interior to view. Fig.2 is a horizontal section on the line of Fig. 1. looking in the direction indicated by the arrows.

In carrying out the present invention, I provide an ordinary gasolene motor which has the lower-part constructed with a casing 1 the sides of which have bearings 3 in which is journaled a shaft 2 provided at its extremity with a ilywvheel 4. The shaft is provided at its middle with a crank 5 en.-

by a, pitman 6' which is oincd to the shaft by means of a journal 7. The lower member of the journal '7 has a nose 7 the lower face of which is inclined, said nose constituting means for engaging the oil contained in the casing 1 and splashing it up wardly in the direction indicated by the ofrows in Fig. 1.

The oil receiver which is indicated generally as 8 is threaded into or formed iutegral with the lower portion of the engine casing l a little above the shaft 2, as shown in Fig. 1. The extension 9 extends through the wall of the oil receiver of the engine to a sufficient extent to expose the opening at the inner end of the extension and afford a backward track for the oil into the re tom extend pipes 10 ceiver 8. From the receiver 8 near the botwhich project around the lower portion of the motor to the bearings 3 of the main shaft. 2. The pipe 10 as well as the lower part of the oil receiver, 8 is preferably filled with cotton or other suitable fibrous substance indicated at 11, thus attording a suitable filter for the oil. To altord ready access to the interior of the re ceiver 8 I provide a threaded plug 12 in the top thereof which can be easily removed. whenever necessary.

It is to be understood that that portion of the structure constituting the present invention can 'be applied readily to an engine already in use. This is done by boring a hole in the casing l. and inserting the tubular nipple or extension 5" and connecting the receiver 8 to the hearings or journals 3 by means of the pipes 10. By then placing a lubricant in the casing 1 and starting the motor it will be seen that, as the cranlr shaft rotates, the nose 7 will splash the lubricant upwardly as indicated by the arrows. A portion. of the lubricant will. gravitate into the inlet end of the opening in the-entension 9 and will thus How to the receiver where it will be strained through the fibrous altering material 1n the casing and Wlll be directed from said casing through the pipes 10 to the bearings. It will be noted that the extension 9 is so shaped as to be extended. readily into the casing and that the p \SfifG leading through this extension has its inlet formed in the top of said extension so that oil when thrown upwardly is free to gravh tote into the inlet end of the passage.

It is to be understood that it is not necessary to ,place the fibrous filtering material in the pipe 10 as, if desired, said material can be located solely in the receiver 8 or, if 7 preferred, solely in the pipe 10.

Having thus described my invention what I claim and desire to secure by Let tcrs Patent is:

The combination with a crank shaft, and means for rotating the same, of a casing housing the crank portion of the shaft, means movable with said crank portion for splashing upwardly the lubricant contained in the casing, and a lubricating attachment including a receiver, a nipple extending therefrom and insertible into the wall of :bhe casing, said nipple having a passage extending therethrough and provided with an inlet in the tsp of "the nipple and within the m the presence of two Witnesses.

In testimony that I claim the foregoing as I my own, I have hereto afiixed my slgnature l
